RTFM is Internet-speak for "Repeat the first message". It is used when the message did not transfer over the Internet properly. If someone tells you to RTFM, be patient with them, and copy-and-paste your original message several times. Also, typing the message with capslock on will improve the chances that it will get through (similar to yelling at a brick wall, telephone, or foreigner).
